Central Arizona DX Association


Next Meeting

We are the largest ham radio DX club in Arizona with over 120 members, many of whom are on the ARRL's DXCC Honor Roll.  We have several members who have traveled to distant places to put "rare" countries on the air.  We encourage any ham interested in DXing to join our club and learn about the many aspects of talking to hams around the globe who share this amazing hobby with us.  Founded in 1974, we are an ARRL-affiliated club.

Our next meeting is on Thursday, August  4th, at the PERA Club.  Our program will be about how new technology is being applied to ham radio.  Larry Loen, WO7R, will tell us about Raspberry Pi (not a dessert) and Arduino and how it is being used to remotely operate ham stations as well as other applications for the shack.

Come join us in the cool confines of the PERA Club.  There will be drinks and snacks at the break (chocolate cake is all gone).

As always, you are welcome to arrive early to socialize.  The meeting and presentation will begin around 7:00 pm.

Thank you to Rex, NR6M, for providing us with the 3XY1T video by the Italian DXpedition Team.  They did an excellent job of documenting their trip to an island off the coast of Guinea in West Africa where they made over 90,000 QSOs. 

One of the highlights was hearing their high quality recordings of the pile-ups on both CW and SSB.  It never ceases to amaze me how massive pile-ups can become and how important it is for the operators at both ends to be disciplined in how they operate to keep the QSO rate moving along at a rapid pace.

We also got to hear a classic British piece of 60’s radio humor by comedian and BBC stalwart Tony Hancock.  In “The Radio Ham” he portrays a newly minted ham in the good old days talking to his ham friends around world after replacing several “valves” (tubes) in his homebrew radio.  He stumbled upon a “Mayday” call from a yacht in distress.  What followed was a series of fumbles and landlady encounters that had us in stitches while he desperately tried to enjoy his one and only chance to be a ham hero.

From My DX Summit


Please join us on the CADXA Repeater at 0200Z on the Thursday nights when the club is not meeting.  If you can help out occasionally as the Net Control Station (NCS), please send an email to KY7M and let him know.

President's Message

July Meeting Recap

Ah, the "summer doldrums" of DXing are here again just like the summer monsoon in Arizona.  It is too hot for most antenna work outside and there isn't much DX to work in the shack.  I have been keeping myself busy with the annual 13 Colonies event on July 4th week and watching 6 meters for any sporadic E openings.  Yesterday yielded my first JA contacts of the year on 6m during a short afternoon E opening.  I got five JAs in the log before the sound of static was the only answer to my CQs.

I was encouraged today to see the solar flux number actually get above 100 for the first time in many weeks.  Fingers crossed that it will keep improving along with days with at least a few sunspots rather than a barren sun as we have seen over the past few months on many days.

I will be heading to Williams for the big hamfest this year.  It will be my first time to Williams and I will be taking along some new CADXA brochures and business cards hoping to recruit some new members for CADXA.  I know that Reinhard, K7RGG, and Jess, AI9L, will both be there to check DXCC cards and I expect to see a few more CADXA members up there in the cool pines.

I had an article published in the July-August ARRL National Contest Journal about my experience operating the N5IA(SK) 160m 8-circle array in the CQWW 160 CW Contest back in January.  It recounts my thrill of catching a spotlight opening to Europe on Top Band a few days before the contest that I will never forget.  I logged 100 stations in Europe that night, something that I doubt I will ever repeat. 

The August meeting will be very educational.  We will have Larry, WO7R, teaching us about some of the new technology that has helped revolutionize our hobby.  I have been hearing about Raspberry Pi and Arduino applications for the past year and Larry will bring them to life for us.  CU there.


Lee, KY7M
